Document Summary

After you recover from an illness, you develop immunity to that virus: you"ll never get that virus again. Skip the sick part - that"s what vaccination is all about. Even minor illness creates damage: scarring can interfere with your health. We live in a microbial world: there"s more bacterial cells on the average person than human cells, human body is under constant attack, without a defense the microbes win, immune system defends us. Immune system uses many weapons: poisons. Used to kill things that get into our bodies. Innate immune system provides an immediate response: non-specific reaction. Immediate maximum response: cold symptoms caused by innate immune system. Innate immune system responds to damage: tissue damage --> release of cytokines (signaling molecules that tell the body there are other cells invading it) --> inflammation redness swelling and. Leukocytes destroy invaders: eat the bacteria. Inflammation gives easier access for immune cells. Adaptive immune system is selective: lag-time between exposure and maximum response.
